10 ancient pyramids around the world
A pyramid is a structure whose outer surfaces are triangular and converge to a single point at the top, making the shape roughly a pyramid in the geometric sense. The base of a pyramid can be trilateral, quadrilateral, or of any polygon shape.
For thousands of years, the largest structures on Earth were pyramids, constructed across the globe by various ancient civilisations, with the largest pyramid by volume being the Great Pyramid of Cholula, in the Mexican state of Puebla.
